You can not check the Discord user’s last seen time but can see the online status if the status is set to “Online” to be viewed. If the user joins the server by accepting your invitation, you can track his online status, active session durations, etc.
Discord Online Tracker:
Just know that tracking the online status of users’ profiles in a Discord server and determining when they were last online can be done manually.
Step 1: First of all, open the Discord application and ensure that you are a member of the server whose users’ online status you want to track.
Step 2: Then, just navigate to the server’s member list or user list. This list typically appears in the right-hand sidebar of the Discord interface.
Step 3: After that, you can manually observe the status indicators next to each user’s name. Users who are currently online will have a green dot next to their names, while offline users won’t have a dot or will have a gray dot.
Finally, by keeping an eye on this member list, you can determine when a user was last online based on the presence or absence of the green dot.
How do I monitor Discord activity?
To view the private activities of a Discord profile, you need to install an app on the target’s device physically so that you can remotely monitor the target’s Discord profile activities without him knowing about it.
